IPC: H03H11/48
Filed: 1995-02-28
Abstract: PCT No. PCT/DE94/00734 Sec. 371 Date May 15, 1995 Sec. 102(e) Date May 15, 1995 PCT Filed Jun. 28, 1994 PCT Pub. No. WO95/01671 PCT Pub. Date Jan. 12, 1995A circuitry arrangement for a resonant circuit that may be completely monolithically integrated and electrically tuned has a differential amplifier stage with two transistors T1,T1' fed by a constant current source I0 that are differentially loaded at their collectors by a voltage-dependent capacity and inductively loaded in relation to the circuit ground by a pair of emitter followers T2,T2' with electrically adjustable impedance that act upon the base. To implement the electrically adjustable impedances, transistors with associated resistances are provided (for example a pair of emitter followers T3,T3' with base pre-resistances R1,R1') which may be adjusted by control currents (for example I1I1') . The voltage-dependant capacity is implemented by transistors T4,T4' whose short-circuited emitters and collectors are connected so that the circuit node thus obtained is applied to the circuit ground through a voltage source U1. This circuit arrangement may also be used in a controllable oscillator by interconnecting two resonant circuits in a loop. The output signal of the first resonant circuit is used to control the second resonant circuit and the output signal of the second resonant circuit is inverted and used to control the first resonant circuit. Thus, two signals may be tapped at the outputs of both resonant circuits. The frequency of said signals may be varied by a control voltage and their frequency-independent phase difference equals  pi /2. An advantageous implementation of such an oscillator is obtained by decoupling the output signals of both resonant circuits through two identical output drive stages.

Abstract: Alkyl aluminium compounds are prepared by treating a non-a -olefin (as defined) with a low molecular weight alkyl aluminium compound (as defined) using as catalyst a compound of Groups IV(a), V(a), VI(a) (i.e. Ti, V and Cr groups).  The non-a -olefin is defined as an olefinic hydrocarbon or mixtures thereof wherein at least 40% of the molecules have a non-terminal olefinic double bond.  The mixture may contain up to 50 mol. per cent of olefins of chain length equal to or less than that of one or more of the alkyl groups of the aluminium compound.  The alkyl aluminium compound is defined as having alkyl groups with fewer carbon atoms than the non-a -olefin employed in the process and may have one or two H atoms attached directly to aluminium.  The catalyst may be a halide preferably the chloride and/or a compound having an oxygen atom linking the metal with a carbon atom.  More particularly the catalyst may be an alcoholate, a chelate, or a phenolate e.g. methylates, ethylates, propylates, isopropylates, phenolates, cresolates, acetylacetonates, salicylates, benzoylacetonates, 2-furoylacetonates; of Ti, Zr, V, U, Cr, Th, W, Ta, or Nb.  The low molecular weight alkyl aluminium compound is preferably tri-isobutyl aluminium but may also be tri-ethyl, propyl or n-butyl aluminium, di-isobutyl aluminium chloride or diethyl aluminium hydride, the preferred compounds having alkyl groups containing at the most 4 C atoms. The non-a -olefins suitable for the process are but-2-ene, pent-2-ene, hex-3-ene, oct - 2,3 or 4 - ene, dec - 5 - ene, tridec-6-ene but preferably having at least 6 C atoms. The non-a -olefin may be obtained (a) by dehydration of an alcohol or mixture of alcohols; (b) by thermal or catalytic cracking of hydrocarbon feedstocks (c) from the residue left after removal of a -olefins by polymerizing with a Ziegler catalyst.  The non-a -olefin and the low molecular weight alkyl aluminium compound may be used in molar ratio 1.5: 1 to 10: 1 and the catalyst in amount 0.05 to 10% but preferably 0.5 to 5% mol.  The reaction temperature may be 50-250 DEG  C. but preferably 100-150 DEG  C. whilst preferred reaction conditions are 0.1 to 2% mol. of catalyst at a temperature of 150-200 DEG  C. In examples 1-3, 1-octanol is dehydrated with 100% phosphoric acid and the octenes mixed with tri-isobutyl aluminium. TiCl4 was added to the mixture, which was then heated and the isobutene produced collected in a cold tap.  In other examples various octenes are used whilst examples 15-53 relate to various catalysts used in processes involving octenes.  Primary alcohols are made by the oxidation of the alkyl aluminium compound prepared as above, to form an aluminium alcoholate followed by hydrolysis of the alcoholate.  In an example the reaction product from a mixture of non-a -octenes is oxidized by bubbling in air and then hydrolyzing with 10% hydrochloric acid, to give 1-octanol after separation and purification. The preparation of 1-octanol is exemplified using various catalysts and starting materials.  Specifications 827,901, 941,016 and 993,666 are referred to.

Title: Improvements in or relating to a process for removing sulphuretted hydrogen from gases
IPC: C10K1/30
Filed: 1952-01-17
Abstract: <PICT:0708972/III/1> In a process for removing hydrogen sulphide from fuel or like gases the gases are contacted with a bed of purifying material, for example iron oxide or active carbon maintained in a purifying zone as a fluidized bed by the gases to be purified, purifying material being continuously withdrawn and returned to the purifying zone after regeneration by removal of sulphur therefrom. The system shown in Fig. 1 has a purifying zone 3 with two superimposed fluidized beds of iron oxide 4 and 6, the gas to be purified enters at 2 and purified gas leaves at 14 after passing through a solids separator 12.  The purified gas is filtered at 15 and a portion may be returned to the inlet 2 through valve 16 to maintain a constant volume of gas passing through the purifying zone. Sulphided material is withdrawn through 8 and transported by a stream of air admitted through line 31 to a fluidized re-oxidation vessel 18 where by treatment with the air from line 31 and additional air admitted through line 46 the material is revivified.  The revivified material is in part returned to the purifying zone 3 and in part passes to a second revivification zone 39 where by air admitted through line 40 the material is completely re-oxidized before passing to a regeneration zone for removal of the sulphur liberated by the re-oxidation.  Fresh oxide and/or regenerated oxide is introduced into the reoxidation vessel 18 through a hopper 34 which also receives the purifying material from the purifying zone 3 for revivification after separation from the air in a separator 33.  The purifying material from the second revivification zone 39 is treated for recovery of the sulphur either by evaporation of the sulphur by hot inert gases or by burning the sulphur di-oxide.  The evaporation of the sulphur is carried out while maintaining the purifying material as a fluidized bed by means of hot inert gases, for example combustion gases containing little or no free oxygen, at temperatures between 200-400 DEG C.  The sulphur is separated from the inert gases by cooling and the inert gases may then be recycled for further use. Sensible heat in the regenerated purifying material may be recovered by appropriate heat exchange before the material returns to the purifying system.  When the sulphur is recovered by combustion the sulphur-laden purifying material is treated in one or more dense fluidized layers with air or as a gas containing free oxygen.  The combustion temperature is controlled between 200-400 DEG C. by providing a water jacket around p  the combustion zone to remove excess heat.  The sulphur di-oxide may be used directly or in a sulphuric acid plant after passing through a filter formed by small pieces of coke.  The regenerated purifying material after cooling is returned to the purifying system.

Title: An arrangement for photographic cameras
IPC: G03B9/08
Filed: 1956-01-16
Abstract: 786,184. Photographic cameras. DECKEL, H., and DECKEL, F. W. Jan. 16, 1956 [Feb. 1, 1955], No. 1398/56. Class 98(1) In a photographic camera, the diaphragm setting member can be adjustably coupled with either the shutter speed setting member or the focusing member. As shown in Fig. 2, focusing ring 16 is threaded into a flange 12 on the camera body, and imparts axial movement to a tube 18, which is held against rotation by a plate 30, entering a slot in the tube. The shutter housing 34 is mounted on a ring 22 carried by tube 18, and includes a shutter speed setting ring 42 and a diaphragm setting ring 40. Ring 40 is connected to a coupling ring 48, which rotates between a flange of a ring 20 fixed to tube 18, and a skirt 44 of the shutter speed setting member 42. A follower ring 94 is rotatably mounted on ring 20, and is connected to the focusing ring 16 by means described in Specification 786,185 whereby ring 94 is driven by ring 16 in such a way that the angle through which it turns is proportional to the distance indicated on the scale on ring 16. A coupling claw 54 is slidable longitudinally on ring 48, and has teeth at both ends which engage corresponding teeth 46 on the skirt 44 of the shutter speed setting member 42, or teeth 124 on ring 94, according to its position. A slide member 66 (Figs. 5 and 6, not shown) controls the movement of the claw so that ring 48 may be coupled with either the shutter speed setting member or the focusing member (through ring 94). In either position, the claw'54 may be moved for adjustment, but the amount of movement possible is not enough to engage the other member. When photographs are to be taken by flashlight, the rings 48, 94 are coupled and are relatively adjusted in accordance with the guide member for the flashbulb. Thereafter when the camera is focused at any distance the diaphragm aperture is also varied through the coupling to keep the product of diaphragm aperture and focusing distance constant. Under other lighting conditions, the rings 48, 42 are coupled and are relatively adjusted in accordance with the light intensity. Thereafter the shutter speed and diaphragm aperture may be varied together without altering the effective exposure.
